All four were arrested without incident, Pollock said. One of the four knew Turner, and one was a documented gang member. Turner, however, was not a gang member.

Turner was shot with a handgun, Pollock said. He would not discuss the circumstances leading to the shooting, he said.

Turner’s last Facebook post was made on March 29, and his father reported him missing on April 6.

In a phone interview with The Eagle on Friday, Turner’s father expressed thanks to authorities working the case and to the tipster who aided in the arrests.

He added that he fosters “no hate or animosity toward anybody,” including the suspects and their families.

“They’re innocent until proven guilty,” Frank Turner said of those accused in his son’s deaths. “We’re going to let the justice system play out.

“This was some young people making some decisions that cost a young man his life.”

All four suspects are being held on $1 million bond in the Sedgwick County Jail, records show. Spencer, Wright and Nguyen were all arrested on suspicion of first-degree murder. Jackson is being held on suspicion of aggravated assault.

As of Friday afternoon, the case had not yet been presented to Sedgwick County District Attorney Marc Bennett’s office for formal charging, D.A. spokesman Dan Dillon said by e-mail.
